What indicates a higher acidity level on the pH scale?

Explanation:
A pH level of 4 indicates a higher acidity level because the pH scale is logarithmic and ranges from 0 to 14. In this scale, lower pH values correspond to higher concentrations of hydrogen ions (H⁺), which are responsible for acidity. A pH of 7 is considered neutral, while values below 7 represent acidic conditions and values above 7 represent basic (alkaline) conditions. Therefore, among the given options, a pH level of 4 signifies a stronger acidic solution relative to the others listed, which range from neutral to basic.
